' .eppllaetion filed Zulylfi, 1917. Serial l lo. 186,794.

To all whom it may concern: Be it known that l, Jenn J. HINES, n citizen ot the Dominion of Canada, residing at Halifax, in the Province of Nova Scot-is end Dominion of Canada, hove invented new and useful Lnproven'ients in Projectiles, of which the following is d, specification.

present invention pertains to projectiles; end it has for its general object to provide e, projectile embodying reliable means for assuring the explosion of the projectile irrespective of Whether it lands in the Water or brings up ngeinst an obstruction.

A seeondery ohject ot' the invention is the provision in e projectile of improved means for locking the firing pin With a View to precluding a premature explosion; the seid rneens heing constructed and arranged to be actuated by centrifugal motion of the projectile incidentnl to its flight through the eir, and losing con hined With means for fasten ing it out of engagement With the firing pin alter it is once Withdrawn iroin the same so as to contribute to the explosion of the projectile when it enters Water or strikes a. vessci or other obstacle in its path.

Other objects and practical advantages of the invention will be fully understood from the following description and c-nims when the some are read in connection With the drevvings, accompanying 'l forming part of this specification, .c

Figure l is e side ole tile constituting the prel oil my invention.

2 is an enlarged, l; central section oil. the she Fig. 3 is e. fragment non, taken in the some plnne as illustrating the position the locltin inenns 101' the firing pm nssulnes and in which. it is secured incidental to the flight of the projectile through the air.

filimiler numerals of reference designate corresponding parts in all of the views of the drawings.

The hollow body 1' of my novel projectile is designed to carry a suitable explosive charge and is equipped with the usual exterior hand 2 for the engagement of the lands of n ride so that the projectile will be rotnted about its axis during its flight from the ride to the objective. in its rear end the hody l is provided With e filling aperture 3 end e vent aperture i, normally closed by plugs 5 end h, respectively.

A comparatively large aperture is pro vided in the forward end of the hotly l, end" is closed by e plug '7, hereinafter rererred to in detail.

Suitably fixed to and arranged within the body 1 is e cylindrical portiond open to the interior of the body, end provi ed. vvith e lining 1.0, of brass or other suitable meteriel. 'lhe chernher 11 in the reer portions of the cylinder 8. and llmiileiplll is adopted to contain a. primer; end it't iillelso he noted that chamber 11 is provided in the forward ortion of the lining and in 'front ot the eddy portion 8.

' Formed in the body 1 are four (more or less). openings 19 which one in registration with apertures 20 in the lining 10 and are designed when the projectile enters 9. body of sister to conduct u eter to'the seid chemher ill j At i l in the lined cylinder is a, diaphmgn'l, preferuhly of ruhher or rubber ()OlllPOSlijlOIl, and heel: or sold diaphragm is e detonator 13 or other suitehle means which when struck by the firing pin Will serve to fire the primer in chamber 11 and through said primer explode the charge in the hollow body 1.. Qps posed to the forward side of the seid'diaphragm is a. spring 14;, end in front of said springis a; piston 15, equipped with e gasket 16. The piste is inte ral with or otherwise fined firing pm 17, end the seid pin is pro: with preferably shipped enlargement 21d.

For the of norinnlly holding the firing pin ewes from the detonetoi"1l, 1' provide the rndinlly movable latch- 931, hacked the spring 22;, end in order to; re tain tin said let-ch 21 out of engagement With the enlargement 18, Fig. 3, ll rovide the movable reteiner 23, hacked y the spring 24.

At 25 the plug '2' is chambered, end secured by a fine threed in said chamber is or plug 26 which is preferably of steel so as to serve as e striking ping and is provided with a rear extension nlined with the firing pin i'l.

The spring 149 may he'of any desired tension according to the depth in the Water at. which it is desired to explode the projectile;

In operation the projectile is fired from a suitablyeleveted piece of ordnance, and during its flight through the air the rotation of the projectile about its axis Will-throw the latch 21 outwardly, against the action of the spring 22, and thereby release the firing pin 17, and when the latch is so thrown outwardly the retainer 23 will assume a position between the latch and the firing pin, Fig. 3, and in that way effectually prevent the latch from interfering with the subsequent movement of the firing pin.

If the projectile lands in the water, which it will enter point first because of the forward portion of the projectile being comparatively heavy, the Water entering through the four (more or less) openings 19 will occupy the chamber 11 and either alone or in combination with some chemical adapted to expand under the action of water will. act against and force the piston rearwardly and thereby cause the pin 17 to strike the cap claim and desire to secure by Letters Pat-' cut, is: r

l. The combination in a projectile, of a body, annovable firing pin arranged therein and having a stepped enlargement, a latch movable rectilinear-1y in a radial direction in the body by centrifugal force due to rotation of the body about its axis and constructed and arranged at its inner end to engage the stepped enlargement of the firing pin and normally hold said firing pin against movement, and a spring-pressed retainer movable rectilinearly at right angles to the latch and adapted when the latch is moved endwise outwardly to assume a position in front of the latch and hold the same out of engagement with the stepped enlargement of the firing pin.

2. The combination in a projectile, of a body, a movable firing pin therein equipped. with a piston, means constructed and ar ranged'when the projectile enters a body of water to enter the projectile and cause firing movement of the firing pin, a striking plug secured by weak means in the nose of the body and adapted on impact to be forced rearwardly in the body and to force the firing pin in the same direction, a latch movable in the body by centrifugal motion thereof and constructed and arranged to normally hold the firing pin against movement, and retaining means constructed and arranged when the latch is disengaged from the firing pin to hold the latch out of engagement with said pin.

3. A projectile having a piston cylinder, a diaphragm interposed between said cylinder and the interior of the projectile, a piston movable in the cylinder, at firing device movable with the piston, a cap at the opposite side of the diaphragm, with reference to the firing device, and means for enabling water to enter the piston cylinder when the projectile entersa body of Water.

4:. A projectile having a piston cylinder, 0. diaphragm interposed between said cylinder and the interior of the projectile, a piston movable in the cylinder, a spring interposed between the diaphragm and the piston, a firing device movable with the piston, a cap at the opposite side of the diap ragm, with reference to the firing device, and means for enabling water to enterthe piston cylinder when the projectile enters a body of water.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
